Dynamic Trust Scorer Test

• Checks whether the function maintains a trust score (0–100) per session (src → dst)
• Learns a baseline packet rate using a sliding time window
• Detects trust violations when deviation exceeds 1.5× baseline
• Checks with regard to different types of attacks(Normal Behaviour , Violation Burst)
• Applies exponential penalty for consecutive violations
• Rewards normal behaviour with gradual recovery
• Blocks the session and rejects the packets if trust score is below the threshold

Components used: Dynamic Trust Scorer (DTS)
